Did you switch off the light on Earth Hour?

I was quite surprise to notice that there’s really a lot of people who are aware of it and really switch off the lights but there are some might not aware of it, some might just ignore it and some took the idea wrong and organize big event (which waste more electricity and energy and its soo wrong ) and some have no choice but to turn on the light.

Do they need to? I thought most of them are already accustomed with saving electricity since like, forever?
Though their reason of doing so is purely financial, they’ve already, though inadvertently doing their part while we “youngsters” go around wasting electricity unnecessarily just cos we can afford it.
